Serial No.

To all whom it may concern:

Be it known that I, Josnrn KRAUs, a citizen of the United States,residing at Anaconda, in the county of Deerlodge, State of Montana, haveinvented certain new and useful Improvements in Filter-Mass VVashers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, suchas will enable others skilled in theart to which it appertains to make and use the same. I

This invention relates to filter mass washers and more especially toanapparatus of this character for removing deteriorated waste and otherimpurities from a filter mass, and is an improvement on my applicationof similar nature filed June 15, 1910, s. N. 566,991.

Another object of the invention is to provide eiiicient means forthoroughly mixing the water and mass composed of pulp and cotton, andfor continuously washing the mass and removing the impurities therefrom,after the beer has been filtered there through, whereby a desirable andcomparatively pure product is obtained. 7

A further object of the invention is to provide a device of thischaracter which will occupy a small amount of space and which may bereadily set up and cleaned when desired, at the same time being cheapand economical to manufacture.

Further objects and advantages will be apparent from the followingdescription, and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the, invention.

In the drawings: Figure 1 is a side elevation of my improved apparatus,partly in section to more clearly illustrate the same. Fig. 2 is a planview of the device. Fig. 3 is a detail sectional view of a sieve used inconnection with my apparatus. Fig. 4 is .an end view of the sieve. Fig.5 is a detail view showing the manner of uniting the stationary andrevolving parts of the operating. shaft for the tank. Fig. 6 is a sideelevation of a fragment of the driving gear.

Referring more particularly to the accompanying drawings in whichsimilar characters of reference designate corresponding partsthroughout, 10 indicates a suitable vertical tank, preferablyconstructed of metal and provided with a cover 11 whi'chis fitted overthe upper end of the tank or otherwise secured thereto, said tank beingsupported by means of suitable legs 13 which are attached to itsinclined bottom 12 and which rest upon the base member 14. The tank isprovided centrally with a vertical hollow shaft 15, the lower end ofwhich is received by and rigidly secured to a ground bearing 16 having atapered lower face disposed and supported upon a base arch 17 havingsuitable openings therethrough to allow the escape of the mass under theaction of suction caused by the continual flow of water or steam. Thelower end of the shaft 15 stops short ofa stationary tube 18 which iscarried by the base arch 17 and securely held from rotation. Said hollowshaft 15 is provided" with a plurality of bent pipes 19 disposed uponthe shaft and secured thereto in stepped relation by means of sleeves 20at spaced distances from the lower end of the tank and below the coverthereof. The pipes 19 have their free ends 21 turned downwardly and bentin a direction opposite to the rotation of the shaft 15, as will beclearly apparent by referring to the drawings.

The stationary tube 18 is disposed through v the sleeve 22 which isadapted to form and surround a space through which the mass may bedrawn, and which has attached thereto the three way coupling 23 to thebottom portion of which extends the stationary tube 18 where. it isdetachably fitted for communication with the supply pipe 24.

By means of the supply pipe 24 water or steam is admitted through thehollow shaft 15 and through the pipes 19, previously mentioned, it beingunderstood that the water or steam applied thereto will from thepressure thereof shoot downwardly from the down turned ends 21 of saidpipes 19 so as to thoroughly mix the water and filter mass.

As will be understood the supply pipe 24: turns upwardly along one sideof the tank and is provided at its upper end with a valve 25 and ahorizontal pipe 26 is pro-,

vided with suitable steam inlet 27 the op-,

posite end of said horizontal pipe having a similar valve 28 and adownwardly extending portion 29 forming an injector 30. In order tocontrol the passage of said mass through the pipe 31 I provide asuitable valve 32 andsaid pipe is further provided with valvedextensions 33rwhereby saidplpe 7 may be properly drained for the purposeof cleaning the same. I Pipes 34 are also disposed in communication withthe supply pipes 24 and 29a short distance from thelr 7 upper ends Wherethe latter are provided with injectors 30. The horizontal-connectingpipe 35 of said upright pipe sections 34 is provided with suitablecontrolling valves '36 and has a suitable inlet 37 for supplying fwaterthereto. It will be understood that water may be conveyed from the mainor any other suitable source, as well as from the source of supply ofthe water for making the steam. V

The injector 38 .is secured in the lower end.

of the vertical discharge pipe 39 which latteriisprovided upon its upperend with a suitable nozzle 40 adapted to discharge the "filter mass intoa revolving cylindrical sieve '41, the injector 3O aiding in thisoperation "said sieve being mounted upon an inclined, shaft '42supported by the bracket arm 43 carried by the cover of the tank. Thesieve 41is arranged parallel with the short horizontal shaft 44, andwill later be more fully described. The injector 38 is formed with arestricted spout and the water or steam discharged therefrom willtherefore escape under increased pressure to carry the mass upwardthrough the pipe 39 and into the sieve 41.

V The sieve 41 is formed with a sheet metal section 44 to receive themass from the nozzle 4 0. It will also be understood that the '"cover isprovided with an opening 45 beneaththe sieve for discharging the filtermass intojthe tank and a sprinkler pipe 46 is disposed above the sieveupon a suitable pipe 47 leading from the horizontal connecting waterpipe 35, the purpose of this I sprinkling pipe being to prevent cloggingof the sieve. 7 7

When 1t 1s deslred to remove the mass from the tank 10 the valve 521sopened,

thus allowing the mass to flow from the discharge pipe 39 and tank 10through the extension 33 to asuitable place.

From the foregoing it w1ll be seen that by my improvedapparatus thewashing opera- ;tion can be continually carried on and the Waste orother impurities can be drawn off and quickly removed from the massthrough which the beer has been filtered, it being understood that theimpurities have been "previously withheld in' the mass when the 7 beerwas filtered therethrough. Thus the filter mass may be advantageouslyused again for filtering beer in clarifying the same, thereby decreasingthe cost of manufacture and greatly enhancing the eco:

nomical value of the present apparatus. .7

I To'rotate "the sieve 41 a .gear 53 is fixed to the shaft 42 and mesheswith a gea'r 54 keyed to the shaft 44, motion being imparted to theshaft 44 by a pulley 55, which "is driven by a belt in the usual manner.To

the inner end of'the shaft 44 is fixed a bev' .eled pinion 56 whichmeshes with a similar gear 57, said gear being fixed to the upper end ofthe shaft 15 so'as to impart rotary movement thereto during the rotationof the sieve. A. combined T and cock 51 is connected to the pipe 39, andserve to remove the mass therefrom when desired. Sup- "p'orted beneaththe sieve 41 is a trough-58, for receiving the liquid from the mass asit i passes'throughthe sieve to thetank, said *troughbeing provided witha pipe 59 to "carry the liquid toa sewer or the like.

' In operating this device the valves 49 and 51 are closed and steamadmitted through the steam inlet valve 27 which steam is forcedthrough'the' pipes'26 past the open valves 28 and downwardly through thenozzl'es 30 and 40. At the same time water is admitted through the pipe37 and flows downwardly through thepipes 34 into the pipes 24 at a pointadjacent 'theend of the nozzles 30 and 40'.

Contact of the steam from with the water flowing into the pipe 24 heatsthe said water and forces the same through the pipe and upwardly throughthe pipe 18 into the hollow shaft 15 and thence out 'wardly through thecurved pipes 19*and expels the same from the ends thereof so as to causethe shaft: 15 to rotate and thoroughly mix the filtermass in thecylinder 10. During this operation the steam from the nozzle-30 heatsthe water entering the nozzle 40 the pipe 24 through the pipe 34 andforces the same downwardly and inasmuch as the valves 49 and 51 havebeen previously closed, the water is forced upwardly through the sleeve22 into the cylinder 10 and not only prevents the, filter mass fromclogging in this sleeve, but also provides the cylinder with hot water.i 7

After the filter mass has been thoroughly washed, the valve 49 is openedand the said filter mass suspended in water is forcedupwardly by thepressure of the steam from "the nozzles 30 and 40 through the pipe 39and into the sieve41 from whence the water is expelled and the filtermass again deposited'into the cylinder 10for rewashing. 7

*wherein the water for washing the filter mass will be heated and forcedinto the washing cylinder and wherein the steam which is used to heatthe water will at the proper time act to force the filter mass andwaterin which it is suspended upwardly to the screening device.

What is claimed is 1. A filter mass washing machine comprising avertical casing constructed and arranged to contain a filter mass, meansto inject water into said casing, a pipe having communication with saidcasing arranged to convey the filter mass from the bottom to the topthereof, means connected to the said pipe and to the injecting means tosupply the said injecting means and pipe with water to simultaneouslyconvey water into the easing and force the filter mass upwardly throu hthe said pipe. 7
